UPDATE (5:05 p.m.): Officials say the commuter train derailment that killed four people in New York caused more than $9 million in damage to the railroad.

Metro-North Railroad says the figure covers repair or replacement of the locomotive, seven coaches and tracks. It does not include any costs from personal injury lawsuits.

The figure was disclosed as the National Transportation Safety Board released a preliminary report on the Dec. 1 derailment. The report did not come to a conclusion on whether human error caused the accident.

It restates previous findings that the train was traveling at 82 mph on a curve that had a 30 mph speed limit. It also repeats that no mechanical problems have been found.

Representatives of the train's engineer have said he may have lost focus at the controls.

A preliminary report by federal investigators on last year's deadly train derailment in New York does not draw any conclusions about what caused the wreck.

The National Transportation Safety Board issued the brief report Tuesday.

It has no major revelations about what happened when the Metro-North commuter train went off the tracks in the Bronx Dec. 1, killing four - including a Newburgh woman - and injuring dozens.

The report restates previous findings that the train was traveling at 82 mph on a curve that had a 30 mph speed limit. It also repeats that no mechanical problems have been found.

Representatives of the train's engineer have said he may have lost focus at the controls. The preliminary report doesn't address that issue.

An NTSB spokesman says new information and a conclusion are probably months away.
